GSO drawtubes coming loose

My GSO EP's have been great, but there is one annoyance with them. The draw-tubes are bad about coming loose. I am thinking about putting some (Red) Loctite, on the threads. Has anyone elese every tried this?

Purpose of the (Red), is that it doesn't come loose without heat, which will never be applied to my EP's.

I've not really had this problem with my GSO EP's. If any do work loose I just tighten them well. I wouldn't permanently cement them in with anything though. Unthreading the tubes can be useful for cleaning the field lens or even for using the tube on another EP.

The drawtube on this Celestron (Barsta) 32mm Plossl shown above is actually from a borked 20mm GSO SuperView. It has no undercut defect and a Revelation Astro (GSO) reducer threads into it perfectly. Oh yeah, and Happy GÅµyl Calan Gaeaf!

Re: GSO drawtubes coming loose

I picked up a small bottle of Theadlocker #42 Blue, from Harbor freight. Yesterday morning I applied a small touch of blue thread locker to the threads with a toothpick, so as not to risk over aplication. After a 24 hour cure, it looks great. The tubes are sealed in place. I only applied the threadlocker, to my Omni, GSO, and Sirius Plossl EP's. Now we will see if an more come loose. I'm thinking that this slight issue is solved.
